DETAILED DESCRIPTION

[0019] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0020] according to Figure 1-5 As shown, this embodiment proposes a fixture for parts processing, including a workbench 1, a top plate 2 and a slide rail 3, the top of the workbench 1 is provided with a top plate 2, and the two sides of the top of the top plate 2 are symmetrically provided with slide rails 3, the top of the slide rail 3 is slidably installed with a sliding plate 4, the top of the sliding plate 4 is provided with a fixed frame 5, and a fixing mechanism is provided between the sliding plate 4 and the fixed frame 5, and a square steel pipe is placed at the bottom of the fixed frame 5, and then the fixing mechanism clamps the square steel pipe at the bottom of the fixed frame 5 to lock its position, wherein the direction of fixing the square steel pipe is perpendicular to the direction of grinding its end face, so that the clamping force acts directly on the square steel pipe, so as to fix the square steel pipe more firmly.

[0021] The fixing mechanism includes a cylinder 6, an articulated seat 7, a wedge block 8 and a clamping block 10. The cylinder 6 is hinged on one side of the sliding plate 4, and the output end of the cylinder 6 is connected to the articulated seat 7. The inner side of the articulated seat 7 is hinged with a wedge block 8. The bottom of the wedge block 8 is fitted and connected to the bottom of the fixing frame 5. The top of the fixing frame 5 is provided with a clamping block 10. The square steel pipe is inserted into the bottom of the fixing frame 5. The cylinder 6 drives the wedge block 8 to move toward the fixing frame 5 through the articulated seat 7. The wedge block 8 moves upward along the inclined surface of the bottom of the fixing frame 5 and cooperates with the clamping block 10 to clamp the square steel pipe. The direction of clamping the square steel pipe is perpendicular to the direction of grinding of its end face. The wedge block 8 and the clamping block 10 directly act on the square steel pipe to fix it more stably.

[0022] A slide groove 9 is provided inside the fixing frame 5, and one end of the clamping block 10 is slidably connected to the inner wall of the slide groove 9. A threaded rod 11 is rotatably connected to the back side of the fixing frame 5. The bottom end of the threaded rod 11 passes through one end of the clamping block 10 and is threadedly connected thereto. The threaded rod 11 is rotated by twisting the threaded rod 11. The threaded rod 11 is threadedly connected to the clamping block 10, and the slide groove 9 limits the moving trajectory of the clamping block 10. Therefore, the threaded rod 11 can drive the clamping block 10 to move back and forth directly while rotating, and the direction of its movement is controlled by the direction of rotation of the threaded rod 11 to adjust the height of the clamping block 10 so that it can adapt to square steel pipes of different heights.

[0023] A telescopic rod 13 is symmetrically connected to one side of the fixing frame 5, and a clamping plate 12 is hinged at one end of the telescopic rod 13. A spring 14 is provided on the outer side of the telescopic rod 13. When the square steel pipe is inserted into the bottom of the fixing frame 5, the outer wall of the square steel pipe first squeezes the clamping plate 12 to move outward, and the telescopic rod 13 and the spring 14 stretch outward at the same time, and then the elastic force of the spring 14 is used to drive the clamping plate 12 to reset. The clamping plate 12 can move toward the outer wall of the square steel pipe to clamp it to adapt to square steel pipes of different thicknesses.

[0024] A rotating motor is installed on one side of the bottom of the top plate 2, and a reciprocating mechanism is provided on one side of the top of the top plate 2. The output end of the rotating motor is connected to the reciprocating mechanism. The reciprocating mechanism includes a turntable 15, a hinged rod 16 and a connecting seat 17. A turntable 15 is rotatably connected to one side of the top of the top plate 2. The outer side of the turntable 15 is hinged with a hinged rod 16 through a pin shaft. A connecting seat 17 is connected to one side of the sliding plate 4. One end of the hinged rod 16 is hinged to one end of the connecting seat 17. The output end of the machine is connected to the bottom of the turntable 15, and the rotating motor can drive the turntable 15 to rotate on the top of the top plate 2. Since the hinged rod 16 is hinged to the turntable 15, the turntable 15 can drive the hinged rod 16 to do circular motion. The hinged rod 16 is hinged to the sliding plate 4, and the slide rail 3 limits the moving trajectory of the sliding plate 4, thereby driving the sliding plate 4 to reciprocate in a straight line, and then driving the square steel pipe fixed on the fixed frame 5 to repeatedly contact and rub with the grinding mechanism to grind the cross section of the square steel pipe clean.

[0025] The workbench 1 is composed of two side plates and a bottom plate. The two side plates are symmetrically distributed on both sides of the bottom plate. The height of the side plates is equal to the height of the sliding plate 4.

[0026] The fixture for parts processing inserts the square steel pipe into the bottom of the fixed frame 5, and the cylinder 6 drives the wedge block 8 to move toward the fixed frame 5 through the hinge seat 7. The wedge block 8 moves upward along the inclined surface of the bottom of the fixed frame 5 and cooperates with the clamping block 10 to clamp the square steel pipe, and the direction of clamping the square steel pipe is perpendicular to the direction of its end face grinding processing. The wedge block 8 and the clamping block 10 directly act on the square steel pipe to fix it more stably.

[0027] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
